Title: Speed detection system of induction motor
Inventor: FUJIKAWA ATSUSHI
IPC: H02P21/00
Filed: 1989-01-09
Abstract: PURPOSE:To permit smooth control within the range of all rotating speeds by a method wherein a value obtained by passing the no-load rotating speed, operated through the operation of a primary flux vector, through a primary delay filter is employed as the no-load rotating speed of the induction motor. CONSTITUTION:A no-load rotating speed, operated by a block 714, is averaged by passing it through a primary delay filter block 718 even if the no-load rotating speed is an intermittent pulse type speed whereby stabilized no-load rotating speed N1 is sent to the block 716. In order to use a slip rotating speed, obtained from the instantaneous value of a torque and corrected by the differential element of the instantaneous value of the torque, as a slip rotating speed N1, the block 719 differentiates an operated instantaneous torque T sent from the block 707 and multiply it by a predetermined given constant Ks' to send it to the block 720 while the block 720 adds the operated slip rotating speed, sent from the block 715, with the correcting value, sent from the block 719 and, thereafter, sends it to the block 716.

Title: Dual reflecting mirror antenna
Inventor: MIZUGUCHI YOSHIHIKO
IPC: H01Q19/18
Filed: 1980-01-11
Abstract: PURPOSE: To avoid the aberration over entire aperture, by forming the main and subreflecting mirrors so that the optical path from the power supply horn located at the focus to the antenna aperture satisfies a given condition.  
     CONSTITUTION: The mirror surface and focus 1, 2 of the subreflecting mirror 3 and the main reflecting mirror 4 are constituted so that they are symmetrical to y-z plane. The aperture corresponding to the focus 2 is present symmetrically with the aperture 8 to yz plane in addition to that to the focus 1. The center of the mirror 3 is extended to the center cross sectional curve 10 present on the yz plane. One point on the curve 10 is selected and the location and slope of the point on the main reflecting mirror are obtained. Next, from the condition that the reflecting mirror 4 is symmetrical to the plane yz, the location and slope on the subreflecting mirror are obtained. Further, the location and slope of the main reflecting mirror are obtained. Further, while changing the location on the curve 10, the mirror plane system can be obtained with similar steps. Thus, no aberration is given to the antenna, since the optical path from the focus 1, 2 to the aperture 8 is constant over the entire aperture 8.

Title: Fuel feeding device for internal combustion engine
Inventor: NAKANIWA SHINPEI
IPC: F02D41/18
Filed: 1989-01-10
Abstract: PURPOSE:To ensure the optimum air-fuel ratio and suppress the discharging quantity of CO, HC, and NOx at the time of an accelerating operation by giving weighted mean to a detected intake air flow rate for each sampling with a weighting coefficient based on an engine speed and an engine load. CONSTITUTION:An intake air flow rate which is detected by a detecting means (airflow meter) B on the upper course side of a throttle valve is sampled each defined time by a sampling means C and, based on this, a fuel feeding quantity is calculated and set by a setting means H to drive a fuel feeding means A via a drive control means I. At the time of an accelerating operation, the detecting means detects intake air quantity which is filled only in a collector portion on the lower course side of an intake dir valve, causing the detected value to greatly exceed the actual intake air quantity taken into a combustion chamber. Therefore, an engine load dependent weighting coefficient by a first setting means D and an engine speed dependent weighting coefficient by a second setting means E are multiplied or added by a third setting means F and, based on this, weighted mean is given to the intake air flow rate for each sampling by a weighted mean means G. Thereby, an air-fuel ratio can be made optimum.

Abstract: PURPOSE:To decrease the total number of processors of a system by monitoring the load of each function and shifting the processors from the processor group with lowerload to the processor group with over load. CONSTITUTION:The processors 11 and 12 form a function A processor group that contains a program of a function A. Meanwhile the processors 13 and 14 form a function B processor group that contains a program of a function B. These processors 11-14 always measure their own age us rates and inform a control processor 10 of the load for the load scattering control. The processor 10 checks the load of the function B, for example, if the overload of the function A is decided. When the low load of the function B is decided, one of both processors 12 and 13 is turned into a processor that scatters the load of the function A.

Abstract: PURPOSE:To measure the depth and size of a peeling part of tiles by tapping the wall tiles with an impact hummer to measure the impact sound, calculating the spectrum of the impact sound and comparing the impact sound with a reference sound spectrum of correct impact sound. CONSTITUTION:An impact sound receiving part 1 is moved along a wall surface by a suspending part 2.

The impact sound signal and the impact position signal are inputted to a peeling status analyzing part 3. The reference sound spectrum of the impact sound is compared with the reference sound spectrum of the correct impact sound to detect the depth of peeling. The position and width of the peeling part are detected on the basis of the position signal. Since the impact sound of the wall surface of the tiles is analyzed and the peeling state can be automatically detected, the depth and size can be precisely detected without manual operation.

Title: Method and system for transmitting graph data in fish-finder
Inventor: KAMEDA TOSHIYUKI
IPC: H04B11/00
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To reduce the probability of display error being generated due to mutual interference of transmission signals by decimating a fish finding data corresponding to a display range at a preset rate and then delivering a processed transmission data. SOLUTION: An A/D converter 101 converts an input measurement signal of fish finding data corresponding to a display range into a digital data which is then delivered to a transmission control circuit 102. The circuit 102 decimates the digital signal depending on a preset rate and delivers a signal affixed with a digital code indicative of decimation rate to a memory 103. When a specified quantity is stored, the memory 103 outputs the stored content which is sequentially converted into analog signal by a transmission circuit 104. Output from the circuit 104 is delivered as a radio transmission signal at the carrier frequency of an oscillator 105. Since the transmission data is decimated, the volume of data is reduced and the transmission time is shortened while lowering the possibility of generating mutual interference.  A display section on the receiving side is surely set with a display range based on a digital code.
